Abstract

detecção de falsificação de reconhecimento facial com dispositivos móveis. são descritos métodos, sistemas e meios para detectar falsificação de reconhecimento de identidade biométrica e/ou validar uma correspondência de reconhecimento de identidade usando a câmera de um dispositivo móvel, processar a imagem facial ou conjunto de imagens do usuário a uma primeira e segunda distâncias para gerar primeira e segunda representações de dados, processar a primeira representação de dados em um modelo preditivo, e comparar a representação de dados com o modelo preditivo.Facial recognition spoofing detection with mobile devices. Methods, systems and means are described for detecting counterfeiting of biometric identity recognition and/or validating an identity recognition match using the camera of a mobile device, processing the user's facial image or set of images at a first and second distance to generate first and second data representations, process the first data representation into a predictive model, and compare the data representation with the predictive model.
